Eberhard Karls University of Tubingen | Austria

Prof. P. Grabmayr has had a distinguished academic and research career with postdoctoral work in the USA and Germany, followed by a long tenure (1983–2017) at Eberhard Karls University, Tübingen. He coordinated international double-degree programs, served as dean of studies for physics and science education, and held advisory roles with BMBF, MIUR, and the Baden-Württemberg education board. He has been an active reviewer for leading journals and evaluator for prestigious institutions including the Humboldt Foundation and the Royal Swedish Academy. His experimental contributions span major facilities worldwide (NIKHEF, IUCF, Texas A&M, RCNP, MAMI, ELSA, Maxlab, focusing on nucleon and nuclear structure, as well as groundbreaking research on neutrino less double beta decay within the GERDA collaboration, where he served as Editorial Board Chair (2005–2018) and task group leader. With 214 publications, including landmark articles in Nature, Science, and Physical Review Letters, and an h-index of 38, his research has significantly advanced nuclear and Astro particle physics. His recent works address muon capture, gamma cascades, and background reduction for double beta decay, reinforcing his central role in probing fundamental questions such as the nature of Majorana neutrinos.
